我在我的Sping Boot 项目中配置Swagger时遇到了问题。我是按照基本的说明来做的，但不知怎么的，它不起作用。
下面是：pom.xml

<!--SWAGGER-->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.4.0</version>
    </dependency>

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.4.0</version>
    </dependency>

Java Swagger配置：

@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build();
    }
}

我得到了这个异常：

在SpringMVC中，如果你想使用Swagger 2，你需要在你的config类中添加“@EnableWebMvc”，如下所示：

@Configuration
@EnableSwagger2
@EnableWebMvc
public class Swagger2Config {
   ……
}

步骤1：删除SwaggerConfig类中的 @Configuration
步骤2：将这样的代码放在/WEB-INF/jetty-dispatcher-servlet. xml中

<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
<mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>

<!-- Include a swagger configuration-->
<bean name="swaggerConfig" class="com.exchangewalk.web.config.SwaggerConfig"/>

这里有两个上下文，默认的spring上下文和spring MVC上下文。如果你使用 @Configuration 注解，它会被默认的spring上下文扫描所获取，它没有RequestMappingHandlerMapping的可见性。这就是为什么SwaggerConfig是一个在MVC上下文中定义的bean是很重要的。

通过删除SwaggerConfiguration类中的@Configuration注解修复了该问题。
仅保留@EnableSwagger2注解

@EnableSwagger2
public class SwaggerConfiguration {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }
}

附言：我的依赖关系：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.1</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.6.1</version>
            <scope>compile</scope>
        </dependency>

当pom.xml中添加了webflux和web的spring-boot依赖项时，我遇到了这个问题：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

在这种情况下，spring-boot-starter-webflux会产生问题。我使用了springfox：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>

对我来说，这足以消除webflux依赖，这是意外添加的，但也许对某人来说，这些信息将是有用的。

u需要附加此依赖项：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
   </dependency>

添加这个插件到你的maven。当我试图从jar运行时，我得到了这个异常。然后我创建了jar与maven-〉安装和运行那个jar，没有错误。希望它能帮助你

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
